create a trigger event and a function module

[ASSY, SOSTHENE]

Hi everybody,

I'm working on appraisal object (APPr_DOC) . There is no trigger event
associated to this object.

I've created 2 events (CHANGED & CREATED)  et write a function module.

When I trigger manually the event using TCODe SWUE, my workflow starts.

Where to put my fonction module to trigger automatiquelly the workflow when
change is made is SAP
using the TCOde APPCHANGE.

Thank you for your help
